Add comparison functions for float16 to match the existing float32
and float64 ones:
float16_eq()
float16_le()
float16_lt()
float16_unordered()
float16_eq_quiet()
float16_le_quiet()
float16_lt_quiet()
float16_unordered_quiet()
These are all just convenience wrappers around float16_compare() and
float16_compare_quiet(). We will want these for AArch23 fp16
support.
